The Android app is already running very smoothly. There are just a few minor things that, in my opinion, could make the experience even better. For example, after starting the app, my calendar always defaults to the holiday calendar, which is write-protected, instead of my personal calendar. Unfortunately, I can’t find a setting on Android to set a default calendar – or am I missing something?
To set a Calendar as the default using the mobile app, you just “press on the word Calendar under the account” you want as the default so it highlights, and “deselect any other calendars”
Then close and reopen the app. That seems to work for me using Android V10.4.4297
